drm/amd/display: Fix DML failures caused by doubled stereo viewport

2020-07-01T05:59:25+00:00

[Why]
Side-by-side and Top-and-bottom stereo configurations fail DML mode
validation due to Viewport exceeded.

This is because we consider the planes as being pipe split in pipe
population so we end up doubling the viewport width, eg. from 4k to 8k.

[How]
These pipes technically aren't hsplit, so add a check for determining
whether is_hsplit should be set.

drm/amd/display: Fix incorrect dcn1 bandwidth calculations

2020-07-01T05:59:20+00:00

[WHY]
Typos cause bandwidth calculation errors, one
of which can cause infinite loop on dcn1 with eDP

drm/amd/display: Avoid pipe split when plane is too small

2020-05-21T16:48:43+00:00

[Why]
The minimum plane size we can support in DML is 16x16. If we try to pass
a 16x16 plane with dynamic pipe split then validation will fail since it
tries to split it into two pipes, each 8x8.

Some userspace doesn't check that the commit fails and because the
commit fails the old state is retained, resulting in corruption.

[How]
Add a workaround to avoid pipe split if any plane is 16x16 or smaller.

drm/amdgpu/display: Fix Pollock Variant Detection

2020-03-09T17:51:03+00:00

Problem Description:
Currently we are checking internal fused rev id with pci rev id. However, fused
internal rev id is the same on all raven2 parts (in which Dali and Pollock were
based on too), thus Pollock detection fails

Fix:
use the pci rev to preform the detection for bandwidth calculations.

drm/amd/display: Fix RV2 Variant Detection

2020-02-25T16:09:12+00:00

[WHY]
RV2 and variants are indistinguishable by hw internal rev alone, need to
be distinguishable in order to correctly set max vlevel.  Previous
detection change incorrectly checked for hw internal rev.

[HOW]
Use pci revision to check if RV2 or low power variant Correct a few
overlapping ASICREV range checks

We might get different numbers of clocks from powerplay depending
on what the OEM has populated.

[how]

drm/amd/display: add Pollock IDs, fix Pollock & Dali clk mgr construct

2020-01-14T15:18:10+00:00

[WHY]
Only a single voltage level should be available to Pollock (min level)
Pollock & Dali get misidentified as Renoir, use wrong clk mgr constructor

[HOW]
Add provided Pollock IDs to ASIC Rev. ID list.
Create new Pollock ASIC RID check, fix RV2 & Dali ASIC checks.
Check RID and set max voltage level to 0 if Pollock is detected.
Work around broken ASICREV_IS_RENOIR, IS_RAVEN2, etc. checks by
performing Dali/Pollock checks before they can be misidentified as RN.
